Ok, this is really simple. All you need is some kale, some oil, and some salt.
1. Wash the kale, and rip the leaves off the rib in the middle, and break them up into chip-sized pieces. If there are thick ribs running through the sides of the leaves, you can remove these too.
2.Put the leaves in a bowl. Pour some oil in. Toss the leaves around so they are all coated. Liberally sprinkle with salt, and toss around again.
3. Put the leaves on a single layer on a cookie sheet (I lined mine with foil for easy cleanup). Bake at 300ºF for about 15-20 minutes, or until crispy. Try one to see if it is crispy enough for you. If they are still a little chewy in the middle, then bake a few more minutes.
